Abstract

Abstract Atherosclerotic calcification and osteoporosis often coexist in patients, yielding formation of bone mineral in vascular walls and its simultaneous loss from bone. To assess the potential role of lipoproteins in both processes, we examined the effects of minimally oxidized low-density lipoprotein (MM-LDL) and several other lipid oxidation products on calcifying vascular cells (CVCs) and bone-derived preosteoblasts MC3T3-E1. In CVCs, MM-LDL but not native LDL inhibited proliferation, caused a dose-dependent increase in alkaline phosphatase activity, which is a marker of osteoblastic differentiation, and induced the formation of extensive areas of calcification. Similar to MM-LDL, oxidized 1-palmitoyl-2-arachidonoyl- sn -glycero-3-phosphorylcholine (ox-PAPC) and the isoprostane 8-iso prostaglandin E 2 but not PAPC or isoprostane 8-iso prostaglandin F 2α induced alkaline phosphatase activity and differentiation of CVCs. In contrast, MM-LDL and the above oxidized lipids inhibited differentiation of the MC3T3-E1 bone cells, as evidenced by their stimulatory effect on proliferation and their inhibitory effect on the induction of alkaline phosphatase and calcium uptake. These results suggest that specific oxidized lipids may be the common factors underlying the pathogenesis of both atherosclerotic calcification and osteoporosis.

  • In vitro, oxidized low-density lipoprotein and several oxidized phospholipid species promote calcification of isolated vascular cells.

    “Work conducted in vitro has shown that Ox-LDL and several oxidized phospholipid (Ox-PL) species promote the calcification of isolated vascular cells45.”

    From Calcific aortic stenosis (2016) · cites this paper as [45]

    The ‘Effect of MM-LDL on CVC Morphology and Nodules’ section reports larger areas of calcifying condensations in cultured vascular cells treated with minimally oxidized LDL. The ‘Effect of Ox-PAPC and Iso-PGE2 on Alkaline Phosphatase Activity’ section reports that ox-PAPC increased a marker of osteoblastic differentiation, but it does not show calcification promoted by several distinct oxidized phospholipid species.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
